[Java-player-users] P/S 2.1, Javaclient2 and PTZInterface

[Maria S. <mar...@go...>]

Hi,

I think I've read similar questions on the list but no answers to them 
so I try again:

I understood that P/S 2.1 and Javaclient are to some extend but not 
fully compatible, right!?
So with these software versions I simply try to control a pan-tilt-unit. 
My problem is that I can read from the ptz once, then move it to a 
desired position and then I can never read from it again, it loops 
forever... surely this can't be a version problem!?

Here's the (very simple) code:


/        // read actual position data
        System.out.println(robot.readAll());
                   
        while (!head.isDataReady()) {           
            robot.readAll();
        }
       
        PlayerPtzData data = head.getData();
       
        float acttilt = data.getTilt();
        float actpan = data.getPan();

        System.out.println("actual pos ["+actpan+","+acttilt+"]");
        System.out.println("moving to ["+pangoal+","+tiltgoal+"]");

        // create a data structure that contains new position data and 
pass to ptz-interface
        PlayerPtzCmd direction = new PlayerPtzCmd();

        direction.setPan(pangoal);
        direction.setTilt(tiltgoal);
      
        head.setPTZ(direction);

        // now read new/actual position data
        System.out.println(robot.readAll());
       
        while (!head.isDataReady()) {   
            robot.readAll();
        }
       
        PlayerPtzData nextData = head.getData();
        actpan = nextData.getPan();
        acttilt = nextData.getTilt();
        System.out.println("final pos ["+actpan+","+acttilt+"]");

If anyone can help me here, that would be great.

Thanks,
Maria
